Foot BathThe main indoor bath is built with local sanukite stone, and there's also a bath set with imported Bad Gastein mineral rock, a rotenburo, a cold plunge, and a carbonated bath that alternates between the men's and women's sides by day. Beyond the baths there's a high-temperature sauna, ganbanyoku (岩盤浴, hot stone-bed lounging), a foot bath, an akasuri (垢すり) body-scrub corner, and a free gym with a treadmill and weights. The water itself is said to be trucked in daily from a spring elsewhere in town rather than drawn on site. Iyashi no Sato Sarai sits right by the Seto Ohashi bridge interchange in Sakaide, Kagawa. One reviewer describes it as a large-scale bathhouse-and-spa complex: the ground floor holds the baths and a second-floor lounge has a TV, loungers, and a light-snack corner. It stays open late into the night, drawing both locals and guests from a hotel next door.

- One standard shower area, - a cold one near the sauna inside, - There are 4 small baths in one room (seems to have a jacuzzi-like effect) - Outside, there is an open-air bath with herbs and - 2 barrels with cool water Saunas: - One large classic sauna - A wet rain sauna. The price was ¥1500, after that you can change clothes and go up to the second floor. #Kagawa
